Three options, and the free one is genuinely usable rather than a trial.
Free
Unlimited notes, folders and tags, the full editor, drawings, images and PDFs, voice recording, note links and graph view, templates, version history, backups and export. No account, no time limit.
Pro
Everything in Free, plus Grape AI with no keys to manage: unlimited AI chat with the note agent, semantic search, voice transcription with speaker identification, AI web search, flashcards, quizzes, mind maps and slide decks, plus cross device sync, the iPhone home screen widgets, the twenty-four themes and priority support. You can also bring your own API keys on Pro if you prefer a specific provider.
Lifetime
A one time purchase that unlocks AI chat with the note agent, semantic search, AI web search and voice transcription using your own API keys. It does not include Grape AI, cross device sync, the iPhone widgets, the themes, memory and personalization, the study tools (flashcards, quizzes and mind maps) or slide decks, and the features that run on Grape servers rather than through a provider, speaker identification, Brainrot videos and infographics, stay with Pro. If you already pay for an AI provider and work mostly on one machine, this is usually the cheaper path.
Choosing
Want sync, the study tools and no fuss, take Pro. Have your own keys, one main device and mostly want to chat with and search your notes, take Lifetime. Not sure yet, stay on Free for as long as you like, and see Set up AI for what the AI setup looks like on each path.
